I shall give it a try and see what happens. Is what you mention
the reason some homebrewers build there own matching networks? Man, in the old days I remember there were a lot of those large var. caps. in the ham shacks, but not anymore. Palstar has a nice unit, but we are talking much bigger investment. Basically, I am just putting up the antennas which I can get away with given the boundry conditions at the qth. Whatever I get, I am sure will be interesting. At this point, I can, at various points here put up the loop, and up on the hill in another "shack" I can probably fit in a double extended Zepp (again with the ladder line). If I can get my archery chops perfected there is still the possibility of a 160M OCF into a tall Eucalytus tree and spanning to a mast on the side of another chicken house. Each antenna situation, will be like an expedition to another little shack on the property, could be fun. Bill K6TAJ 'Doc wrote: Bill, Unfortunately there are no 'magic' lengths for your loop. Something in the neighborhood of 520 feet should work well on 160 meters, 250 - 260 feet for 80 meters. The limiting factor is the 'MatchBox', it doesn't have the impedance tuning range other tuners have because of the small number of inductance taps it uses. (It's 'big brother' has the same limitations, by the way.) The 'MatchBox' being a real 'balanced' tuner is nice, but just not that big'a deal for all practical purposes. In general (meaning that there are always exceptions) the largest loop you can get into the air is the way to go, if you cn 'match' it... 'Doc |
